Abstract
Abstract An oral measuring device is presented which is formed from plastic or other lightweight substance for insertion in the mouth between the front teeth. The device includes a series of top and bottom arcuately shaped grooves from receiving the teeth. Once the insert has been positioned as far inwardly into the mouth as possible, indicia along the side of the measuring device provides a readily visible measurement of the oral opening.
